STED'IFELD, OF BRAINERD, MINNESOTA WINDSHIELD CLEANER Original No. 1,869,880, dated May 15, 1928,8er1a1 No. 181,804, filed January 18, 1927. Application for reissue filed October 19,1928. Serial No. 813,801.

This invention relates to windshield cleaners, and has for one of its objects to provide a novel and simple apparatus through the -medium of which a material, which is soluble in the presence of snow and ice and which will melt t e same may be readily applied to the outer surface of a windshield so as to prevent snow and ice from accumulating thereon in a manner to' obstruct the vision of the driver.

A further object of the invention is to provide an ap aratus of the character stated which shall e adapted to be connected to the windshield wiper so as to permit the application of the soluble material during the op-' eration of the wiper.

With the foregoing and other objects in view, the nature of which will be come apparent as the description proceeds, the invention consists of the construction, combination and arrangement of arts hereinafter full described and claime and illustrated in t e accompanying drawing, wherein:

Figure 1 is an elevational view illustrating the application of the soluble material appl ing apparatus;

igure 2 is a sectional view taken on the vertical plane indicated by the line 22 of Fi re 1;

igure 3 is a sectional view taken on the horizontal plane indicated by the line 33 of Figure 1; and igure 4 is a similar view taken on the vertical plane indicated by the line 44 of Figure 1.

Referring to the drawing by reference characters, 1 designates the windshield of an automobile, 2 the wi er for the windshield and 3 the a 'paratus or applying a material,

0 which is so uble in the presence of snow and ice and which will melt the same to the outer surface of the windshield. The wiper 2,

which may be of an well known or appropriate construction an' of the manually or motor operated type, comprises a shaft 4 which is journaled in'a frame 5 of the windshield 1,

a wiper arm 6 which is secured to the shaft 4, and a rubber strip 7 which is secured in-a holder 8 ivoted as at 9'to the arm.

The so uble material is in bar form. This bar 10 is preferably though not necessarily made of rock salt and is substantially similar in length to that of the wiper stri 7. The bar 10 is carried by a holder 11w ich is open at its rear side and upper end and of which the, lateral sides 11' are inwardly inclined to securely retain the bar 10 therein. The holder 11 is secured to the arm 6 in a manner to position the bar 10 in parallel or substantia ly parallel relation to the wiper strip 7. This connection is established through the medium of an arm 12' pivoted as at 13 to the holder 11, and a clamp 14 carried by said arm and detachably engaged with the wiper arm 6. The clamp 14 is carried by the u per end of the arm 12, and the lower end of tfie arm is pivoted to the holder 11. The clamp 14 comprises a member 14 fixed to and extending laterally from the arm 12, a member 14" connected to the member 14 by a bolt 15 and winged nut 16, and a member 14 is shown vpositioned upon the bolt 15 between the members 14 and 14". The clamp -members 14, 14 and 14 are provided with grooves 17 of different depths so as to adapt the apparatus for application to wiper arms of different diameter and of different cross sectional formation. When found necessary or desirable, the clamp member 14 or the clamp member 14 may be omitted. The

ply t e soluble material to that portion of the windshield directly in front of the driver. The soluble material will prevent the formation of ice on such portion of the windshield and will melt snow falling on the windshield. Furthermore, the apparatus will, as it is connected to the wiper, apply the sol uble material during the operation of the wiper, and the wiper will clear the stated portion of the windshield of melting snow or ice.

It will be further apparent that the apparatus is simple and durable, that it may be manufactured and soldat a comparatively low cost and that it may be readily secured to 5 and will .not interfere with the operation of the wiper.

It should be understood that the drawing is merely illustrative and does not preten to ive exact proportions. Furthermore, the sai drawing is illustrative of a preferred construction, it being my expectation that "various changes and modifications may be made without departing from the spirit and scape of my invention. claim as my invention:

1. An attachment for the wiper arm of a windshield cleaner, comprising a holder for a soluble body adapted to be arranged parallel tolthe wiper arm and in contact with o the lass, and means forpivotally connecting t e holder to the wiper arm.

2. An attachment for the wiper arm of a windshield cleaner, comprising a holder for a soluble body adapted to be arranged parg5 allel to the wiper arm and in contact with the glass, an arm pivotally connected to the holder, and a clam carried by said second arm and enga 'ng t e wiper arm.

3. An attac ment for the wiper arm of a so windshield cleaner, comprising a holder for a soluble body, an arm pivoted to the holder, and a clam carried by said-second arm and. engaging t e wiper arm, said clamp including members provided with grooves of dif- 85 ferent depths for selective reception of they wiper arm, and a bolt for clamping said membersvto the wiper arm..

4. An attachment for the wiper arm of a windshield cleaner, comprising a bar of salt, a holder for the bar of salt, and means for supporting the holder from the wiper arm to position the bar of salt in contact with the. glass of the windshield and in substantially parallel relation to the wiper arm of the cleaner. i

5. An attachment :[orthe wiper arm of a windshield cleaner, comprisin soluble body substantially similar in leng into the wiper strip of the cleaner, a holder for the soluble body,- and means for supporting the holder from the wiper arm to position the'soluble bo d in contact with the glass of the windshe (I and in substantially parallel relation to the wiper arm.

6. A n attachment for a windshield cleaner, comprising a nonifiexible soluble body, and means for sup ortmg said soluble body upon the windshie cleaner so as to cause said to contact with the glass of the windshie d, and to move with said cleaner.

7. Anattachment for a windshield cleaner, com rising a non-flexible soluble body, a hol er for said body, and means for supporting the holder upon the windshield cleaner to position said soluble body in contact with the glass of the windshield and to move with said cleaner.

8. An attachment for a windshield cleaner, comprising a bar of soluble material, a holder for said bar, and means forsupporting the holder u on the windshield cleaner to position sai bar in contact with the glass of the windshield and to move with said cleaner.

9. An attachment for a windshield cleaner, comprisin an elongated bar of soluble material, a older of U-shaped cross-section, adapted to receive said bar, and means for supporting said holder upon the windshield cleaner so that one side of said bar will contact with the glass of the windshield, and to move with said cleaner.

10. An attachment for a windshield clean er, comprisin an elongated bar of salt a holder adapte to receive said bar, said hol er having opposed side walls bent inwardly and one en wall cooperating with said side walls to retain said bar of salt in said holder, and means for supporting the holder uppn the windshield cleaner to position said ar of salt in contact with the glass of the windshield.

In witness whereof, I have hereunto set my hand this 17th da of Se tember, 1928.
